Serum and uterine secretions Na, K, Ca, Mg and P were studied in 15 normally reproducing and in 15 repeat-breeder cows. No cyclical variations were noted for these elements in the serum whereas the normal group showed cyclical and significant K, Mg and P variations (P <0.05) in the uterine secretions. The concentration of the studied uterine elements, with the exception of P, correlated with the concentration of their homologue in the serum at different stages of the cycle. It is believed that the concentration of serum Na, K, Mg and Ca maintains the intrauterine concentrations at the physiological level for the survival of the gametes and the embryo. Significant differences in the uterine concentrations of Na, K and P were noted between the groups at different stages of the cycle. These various concentrations as well as the nonsignificant variations of the uterine secretions might explain the infertility in the abnormal group.
对15头正常繁殖奶牛和15头屡配不孕奶牛的血清及子宫分泌物中的钠、钾、钙、镁和磷进行了研究。血清中这些元素未发现周期性变化，而正常组子宫分泌物中的钾、镁和磷呈现周期性且显著变化（P<0.05）。除磷外，所研究的子宫内元素浓度在周期不同阶段与其血清中的同源元素浓度相关。据信，血清钠、钾、镁和钙的浓度将子宫内浓度维持在生理水平，以利于配子和胚胎的存活。在周期不同阶段，两组之间子宫内钠、钾和磷的浓度存在显著差异。这些不同的浓度以及子宫分泌物的不显著变化可能解释了异常组的不孕情况。
